Specification of Letters Patent.

Patented Mar. 20, 1917.

Application flied September 8, 1916. Serial No. 119,081.

To all whom it may concern:

Be it known that I, PETER SznREMETA, a subject of the Emperor of Russla, residing at Hammond, in the county of Lake -and State of Indiana, have invented cer-,

the rails will be locked together by means of a chair conforming to the shape of the base and web and under-face of the tread of the rail, and a locking device of special construction which,dispenses with bolts and nuts and'aifords a lock permanent in charactor. The joint furthermore embodies features of construction which adapt it when used in connection with a movable frog or switch rail to permit deflection or side movement of the switch rail and possess the same advantages of construction as when applied at the abutting ends of statlonary rails. a

To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in the features hereinafter particularly described and then sought to be clearly defined by the claims, reference being had to the accompanying drawings forming a part hereof, and in which Figure 1 is a plan view invention;

Fig. 2 a horizontal section on line of Fig. 3;

Fig. 3 is a side elevation;

Fig. 4 is across section on line 44 of Fi 3' Fig. 5 is a side elevation showing chair with movable wing;

Fig. 6 a horizontal section on line 6-6 of Fig. 5, and showing in dotted lines shifted position of movable rail;

embodying the Fig. 7 is across section on line 77 of Fig. 5; I

' Fig. 8 is a fragmentary planvlew of the chair, with movable wing removed;

rail-j oint chair.

to take up slack and looseness.

Fig. 9 is a perspective of the movable wing of the chair.

In the drawing the numeral 1 designates statlonary or fixed rails and 2 a movable frog or switch rail, and 3 designates the ar 1 side cheeks 5 corresponding to the web of the rail and which at their upper ends bear against the under face of the tread of the rail so that the base flange of the rail rests upon the base of the chair and its tread rests upon the upper edges of the checks of the chair whereby are formed'two bearlng supports for the rail while the sides of the web of the rail are braced or have bearing against the cheeks of the chair, so

This chair has a base 4 corresponding to, the base-flange of the rail,

that the abutting ends of the meeting rails are prevented from dropping one below the other. The chair and the rails are locked together at the joint by a key 6 consisting of a bar 7 having laterally projecting pins 8 which are passed through registering,

openings 9 formed in the cheeks of the chair and in the webs of the rail at opposite sides of the joint between the abutting ends of the rails, the opposite ends of the bar 7 being bent or curved as indicated at 10 so as to engage or hug the opposite ends of the chair and thus relieve the pins of strains longitudinally of the rails, and the chair cheek next to the bar 7 is formed with a groove 11 for the bar to lie in so as to relieve the pins of vertical strains. A locking pin 12, preferably of spring steel is passed through holes made in the lateral pins so as to hold them in place. The looking key described dispenses with bolts and nuts and securely locks the parts together without liability of the parts becoming loose and a necessity of tightening the parts The chairs 3 may be rigid throughout when to be applied to fixed or stationary rails, or may have a flexible or yielding wing constituting a part or section of one 16 forming a part of the base of the chair and a depending tongue 17 which is preferably dovetail in shape .and adapted to fit 'a dovetail groove or cavity 18 formed in the chair. The base of the chair is formed with a cavity 19 in which is fitted a spiral spring 20 that is formed with an extension 21 adapted to fit in a socket 22 to revent movement of the spring. One en 23 of the spring is fitted in a hole or bore 24 formed in the base of the chair to aid in holding the spring in place and its other end is formed into a loop 25 to receive the tongue 17 of the wing so that when the wing is spread outward the spring will distend or stretch and when the-pressure is relieved the spring will tend to restore the wing to its normal or original position. The wing section is secured to the cheek of the chair by means ofa key 26 fitted in a dovetailed groove 27 formed in the face of the cheek and vertical wall of the wing, said key preferably being made of stiff spring metal and formed with openings or holes 28 which will register with corresponding holes made in the cheeks of the chair and web of the rails to receive the laterally ex- 7 tending pins 29 and 30 of the bar 31 constituting the key for locking the chair and rails together. This key is substantially the same as the key previously described eX- cept that only two of its pins are formed with holes to receive the lock pin, the other pins 30 of the bar being adapted to pass through openings in the lock pin and preferably being slightly deflected from a horizontal, or downwardly as shown, so as to prevent the lock pin from disengaging from the pins. The lock-pin is made of stiff spring metal and has a reduced portion 31 to pass through the holes in the pins 29 and a flattened portion 32 formed with holes 33 to receive the pins 30. The lock pin is thus held against longitudinal movement, and also against disengagement from the pins 30 .as the latter are slightly bent at their ends so that when the flattened portion of the lock pin is sprung into engagement with the pins, the lock-pin is held in place and all the parts securely locked together 50' without the use of bolts and nuts. By securing. the movable frog or switch rail and the chair together as described a slight lat- I e-ral yielding of the switch rail under spring tension is permitted when necessary and when pressure on the rail is relieved the spring lock-pin and the coiled spring will restore the wing to its normal position. The same features of construction and advantages described for the chair applied to the the movable frog or rail the latter being additionally provided with the yielding wing for the purposes specified. As before mentioned the chair with the yielding wing could be applied at all ointsbut for the stastationary rails are found in the chair fortionary rail joints the yielding wing may be omitted and the chair made rigid throughout.

I have illustrated and described with particularity the preferred details of the sev- 7o eral parts but changes can be made therein and essential features of the invention re- 1 tain'ed.

Having described my invention and set forth its merits. what I claim is: 5
